from The Lord of the Rings

The Road goes ever on and on
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can,
Pursuing it with weary feet,
Until it joins some larger way,
Where many paths and errands meet.
And whither then? I cannot say.

from The Lord of the Rings

Gil-galad was an Elven-king.
Of him the harpers sadly sing:
the last whose realm was fair and free
between the Mountains and the Sea.

His sword was long, his lance was keen,
his shining helm afar was seen;
the countless stars of heaven's field
were mirrored on his silver shield.

But long ago he passed away,
and where he dwelleth none can say;
for into darkness fell his star
in Mordor where the shadows are.

from The Lord of the Rings

Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.

Desperate Courage: A Proposed Rule for Halflings.

This rule can be used if falling to 0 Hit Points causes unconsciousness rather than death.

If a halfling loses enough Hit Points that they would fall unconscious but not die, they may make a Saving Throw. Success means that they stay conscious until the end of the combat, or out of combat for ten minutes. If they receive further non-fatal wounds within that period they do not need to make further saves.
 
"There is a seed of courage hidden (often deeply, it is true) in the heart of the fattest and most timid hobbit, waiting for some final and desperate danger to make it grow."

Speculative Map of the Downunderworld

 

The southern settlement marked here as Morborn is said by some sources to be named Melnibourne. Likewise the settlement of Hobartton is sometimes called Hoborea. The Australien sage Son-of-the-Law states that "our home is girt by sea", suggesting a vast underground ocean. Australiens appear to have little or no idea what lies beyond it.
